[Excerpt] Between 1977 and 2007, employment of workers 65 and over increased 101 percent, compared to a much smaller increase of 59 percent for total employment (16 and over). The number of employed men 65 and over increased by nearly twice as much, climbing 147 percent. While the number of employed people age 75 and over is relatively small (0.8 percent of the employed in 2007), this group had the most dramatic gain, increasing 172 percent between 1977 and 2007.
